CLAMP.

Application filed June 8, 1925. Serial No. 35,695..

My invention relates to a clamp.

The object of my invention is to provide a binding means for the end of the tube next to the scalp to prevent excess heat. from reaching the scalp when givlng a permanent wave.

A further object of my invention is to provide a ratchet means eliminating the pos sibility of closing to clamping position without fastening permanent.

A still further objectof my invention is to provide a clamp in which the spring and pawl are integral and easily replaced.

A still further object of my invention is to provide a releasing lever for the pawl, reciprocating to and from the side of the 1 Referring to the drawings; it will be noted that the mechanism is drawn approximately three times the actual size for convenience of illustration.

Fig. 1 is a side view of the clamp, closed normally.

Fig. 2 is an edge View, parts being removed for convenience of illustration.

Fig. 3 is a side view of the clamp partially opened.

Fig. 4 is an enlarged detail view of the pawl and toothed member which is partly in section for convenience of description. v

Fig. 5is an edge View of the clamp when closed as in Fig. 1.

Fig. 6 shows my clamp in action.

The clamp consists of two arcuated members, the said members'functioning as jaws. The jaw 1. is two ply, the plies of which are spaced apart to receivejaw 1 which is the one ply, the said jaws are pivotally connected as at 2, and on the outer or free ends thereof are laterally extending wings 3 and 3' as gripping elements for opening and closing the jaws.

On the side of jaw 1 is positioned a spring 2 having a pawl on the free end and integral therewith. The opposite end of the spring is rigidly attached by means of rivets 4c, the said spring has a curvature as at A so that the end of lever 9 will engage under the spring adjacent the pawls. The said pawl is adapted to engage through an opening 7 in registry therewith to engage with the teeth 8, a plurality of which are embossed in'the side of jaw 1 and the said jaw engaging between the plies of jaw 1 is means to insure engagement of the teeth with the pawl. A lever 9 is pivotally connected to jaw 1 as to B, one end of the lever engages under the sprlng adjacent the pawl, and by pressing on the opposite end as at D is means for disengaging the pawl 6 from the teeth 8 at which time the clamp is free to open shown in Fig. 3.

At the time of applying the clamp it will be opened as shown in Fig. 3 and then placed over the end of a tube and closed as shown in Fig. 6 for the purpose hereinafter described.

To release the clamp, the lever 9 hereto fore described will be operated disengaging the pawl, the movement of which is a transverse motion to that required in closing the jaws by which means the danger of releasing the pawl when the jaws are being closed is eliminated. I will briefly describe the process of making a permanent wave in the hair and the importance of the use of a clam constructed as herein set forth.

To secure a permanent wave I moisten a portion of the hair and wrap it tightly around a rod, which is a part of the permanent wave machine, I then saturate a felt with a preparation that will impart steam, then a tube is placed over the felt and a heating apparatus is then placed over the tube which is the drying process. It will be understood that the inner end of the tube is in close proximity to. the scalp therefore it is very important that the heat and steam be forced to flow from the outer end by reason of the end next to the scalp being clamped to a closed position.

Such modifications may be employed as lie within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a clamp, a two ply jaw and a one ply jaw, said jaws being pivotally connectedso that the one ply jaw will engage between the plies of the two ply jaw, a plurality of teeth on the side of the one ply jaw, an arcuated spring pawl on one side of the two ply jaw, an opening in the side of the two ply jaw to which the arcuated spring pawl is attached, the said pawl engaging through said opening and adapted to engage with the teeth on the side of the one ply jaw, a lever on the side of the two ply jaw to disengage the pawl from the teeth, wings integral and transversely positioned to the plane of their respective plies of the two ply jaws, a wing integral and transversely positioned to the plane of thewoneply jaw as gripping eleopening throngh which eaidpawl will engage, a lever piyo tally connected to the two.

ply jaw for the reciprocation of the pawl, a laterally extending wing on last said jaw adjacent to said lever functioning as a guard for said lever when the jaws are being closed.
